' BABY HIGH CHAIR.

Application filed November 30, 1921. Serial No. 518,861.

To all whom t maz/ concern." n

Beit known that 1,.JoHN W. FRANZ, a citizen of the United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Baby High Chairs, of which the following is [aspecification. i

My invention has relation to improvementsin baby high-chairs, andconsists iny the novel features of construction more fully set; forth inthe specification and pointed 'out inthe claims. l The object of thepresent invention is to provide a high-chair having springs inter` posedbetween the body of the chair and the legsso that said body may begently reciprocated when desired. A further object is to provideahigh-chair that may be con.- verted into a crib at a moments notice bysimply readjusting the parts composing the chair body. Further and otheradvantages will be readily apparent from a detailed description of ,theinvention in connection theV accompanying drawings, in which- Figure lis a side elevation of the chair with the parts shown dotted in theirreadjusted positionv to form a crib; 2 is a top plan of the chair innormal position; F ig. 3 is a front elevation of the chair in normalposition; Fig. 4 is a detail view showing the brackets and rod on whichthe chair back and table swing.

` Referring to the drawings, B represents the chair base on which thechair body C is supported from suitable springs S. The construction ofthe base B forms no part ofthe present invention, as that forms thesubject-matter of UnitedStates Patent No.

1,377,332 issued to Louis G. 'Franz -on May edge of said back. The footrest is pivotally.

mounted on the bottom by hinge pins 7, 7 and the back 6 is alsopivotally mounted on the bottom by hinge pins 8, 8, said foot rest tom 1and project downwardly from ,each` vrear corner thereof, thel freeend'of each ,l

bracket carrying a tubular head 12 havingl a reduced threadedportion 12lextending inwardly at the base of'vvhich' lis a shoulder y13. A hollowtube 14 provided with a medial grip 15 and having a nut 16 positionedover each end is positioned between the brackets 11, 11. The nuts 16,16, are provided with a slotted extension on their inner ends, the slotsr, 7 of each of which receivel pins 17, 17 projecting from each endofthe tube 14 and as the tube is rotated4 thenutswill also rotate and befree lto slide back and forth on the tubewhich movement is necessarysince the outer ends-of the nuts have right and left handV tapsrespectively for receiving the threaded portion 12 of each bracket, saidbrackets alsovhaving right land left threads respectively. y

The back 6 is supported in its normal upright position by a pair oflever arms 18, 18 pivoted at their upper ends to brackets 19, 19 securedto the rear of the back, the lower end of each of said arms 18, 18 beingforked at 20, to receive one end of a brace bar 21, the other end of thebrace bar be# ing pivotally mounted in a bracket 22 fixed to the back ofone side 3 of the foot rest 4. rIhe arms 18, 18 are each'provided with aslot m extending `from the fork 20 upwardly about one-third the lengthof the arm, and when the arms 18, 18 are connected they are mounted onthe extensions 12 of the brackets 11 (that is, this extension passesthrough slot m) in abutting relation with shoulders 13. Now, when thetube 14 is positioned between the brackets and the nuts 16 are screwedover extensions 12', 12 said nuts will be brought against the arms 18and when screwed home, will hold saidk arms in place.

A table 23 is normally positioned across the front of the arms v9, 9,said table having 'a web 24 in each upper front corner and one iio arm25 is provided with a slot p and a bolt 28 is passed through the tube.14e and the slot p of both arms 25, said bolt having a head 29y at oneend, and the other end being threaded t0 receive a wing` nut 30. As thewing nut is screwed tight the lever arms 25, 25 will be drawn tightlyagainst the heads l2, 12 of brackets 11, 1l and secured in place.

From the above it will be apparent that on turning the tube 111 by meansof the `grip 15 the arms 18, 18 will be bound tightly or loosened', thusholding the back in place or allowing it to drop down to the positionshown dotted (Fig. 1) and by turning the Wingnut 30 the table 23 may besecured in its normal position or loosened so that it mayalso be swung'around to the dotted position (Fig. 1). When the back isgdroppeddownwardly in line with the bottom 1 the arms will travel forwardly onthe extension 12 of the brackets 11 and swing the foot rest 4 forwardly,which may then be raised to form a further extension of the bottom 41.)Vhen the parts are in the positions shown dotted (Fig, 1) they areagain locked by tightening the tube 14 and wing` nut 30, and asubstantial crib is formed. It will be observed that when the 'chair isconverted into a crib the arms 18 form a truss with the bars 21, thusinsuring` an absolutely rigid structure. v

Having described my invention, I claim:

l. In combination with a base, a chair body mounted thereon, said chairbody comprising a seat, a back hinged thereto and a oot rest hinged tothe seat opposite to the back, a pair of brackets fixed to said seat, apair of lever arms pivotally connected to said back and having a slidingconnection 40 with said brackets, connecting` rods between said leversand foot rest, saidv back and foot rest being adapted for adjustment toform a continuation of the seat thereby converting,- the chair body intoa bed, the lever arms and connecting rods forming a truss when thepart-s are so adjusted, andy means for clamping the lever arms to thebrackets.

2. In combination with a base, a chair body comprising a seat and a backhingedg thereto, a table disposed to the front" of and in a plane abovethe seat, aL pair of brackets fixed to said seat, a pair oflever armspivotally connected to the back andy having a sliding connection withthe brach-Q ver arms to the brackets, and independent means forclamping` the last mentioned lever arms tothe brackets.

In testimony whereof I hereunto aix my signature.v
